The Sun and Earth

The Sun and Earth are part of our solar system, which is made up of the Sun, eight planets, and various other celestial objects. The Sun is a star located at the center of our solar system, and the Earth is the third planet from the Sun.

The Sun

The Sun is a massive, glowing sphere of hot gas that provides light and heat to the planets in our solar system. It is made up of mostly hydrogen and helium and is incredibly hot, with temperatures reaching millions of degrees at its core. The Sun's energy is created through a process called nuclear fusion, where hydrogen atoms combine to form helium, releasing a vast amount of energy in the process.

The Earth

Earth is the third planet from the Sun and is the only known planet to support life. It has an atmosphere that contains the air we breathe, as well as water in the form of oceans, rivers, and lakes. The Earth's rotation on its axis causes day and night, while its orbit around the Sun creates the changing seasons.
